MaxMon offers a wide range of transducers, categorised into sensors (which monitor things) and actuators (which control things). To help you configure your MaxMon system this page first lists the external sensors and actuators that connect to the MaxMon app via a Quatropus accessory, then the sensors built into the Android phone running the MaxMon app.

Quatropus sensors

Requires Quatropus accessory and a sensor module (see How MaxMon works):

Quatropus actuators

Phone sensors

Built into Android phone running MaxMon app:


QUATROPUS SENSORS


maxmon-plot-loopAlarm loop (equipment tether)

[Quatropus sensor] When used with a special loop adapter accessory a Sensor-C2 can monitor electrical continuity through long 'audio' cables looped through equipment stored outside a monitored property (for example outboard motors or dinghies). Ideal for boat security applications.
 


maxmon-plot-backupBattery backup

[Quatropus sensor] A Sensor-B provides battery backup for a MaxMon system while monitoring battery voltage and mains power. The example graphs show mains power returning after an outage and a sawtooth voltage (as a 'smart' charger charges and conditions the battery). Ideal for monitoring mains power and the health and state-of-charge of 12V or 24V battery systems.


maxmon-plot-humidityRelative humidity

[Quatropus sensor] A Sensor-TRH monitors relative humidity (and temperature). Ideal for guarding against weather damage, condensation, mildew, etc. The graph to the left shows the performance of a dehumidifier in power-saving mode.

 


maxmon-plot-floatLiquid level (float)

[Quatropus sensor] A Sensor-C2 can monitor up to two liquid level (float) sensors. The graph shows a normally closed (NC) float sensor entering an alert state (electrically open circuit), indicating a potential flood condition. Ideal for monitoring boat bilges or basements or rooms prone to flooding.


maxmon-plot-motionMotion (passive infra-red)

[Quatropus sensor] A Sensor-M detects motion by monitoring infra-red or thermal energy (so it also works in the dark). The example graph shows spikes of motion during a 24-hour period. Ideal for security (detecting intruders) or environmental (detecting lack of motion in a kitchen used by an elderly relative) monitoring.


maxmon-plot-proximityProximity (doors & windows)

[Quatropus sensor] A Sensor-C2 can monitor up to two proximity sensors, which are small two-piece magnetic sensors that detect the opening or closing of doors, windows or hatches and are mounted on the door and its adjoining frame. Ideal (but not exclusively) for property security applications.


maxmon-plot-supply-kwhSupply (power consumption)

[Quatropus sensor] A Sensor-S clips around the mains supply cable entering a property and measures total electrical power consumption in the range 0-24kW. It can be used to monitor excessive power consumption or unauthorised occupancy (without invading tenant privacy).

See Q: How do I monitor electrical power consumption?


maxmon-plot-temperatureTemperature

[Quatropus sensor] A Sensor-TRH monitors temperature (and relative humidity). Ideal for preventing property damage due to extremes of temperature, e.g. frost damage, burst pipes, etc. and reducing energy costs by remotely monitoring the effectiveness of heaters. In conjunction with a MaxMon actuator it can act as a thermostat (with remote manual override).


maxmon-plot-voltVolts

[Quatropus sensor] A Sensor-V2 can monitor two voltages in the range 0-30VDC. A special accumulator mode also enables monitoring of the duration of applied voltages. Ideal for monitoring the state-of-charge and health of 12V or 24V battery systems, but can monitor any 0-30VDC circuits, e.g. accumulator mode can be used to monitor bilge pump activity on a boat.


QUATROPUS ACTUATORS


actuator-rf-200x87RF remote control

[Quatropus actuator] An Actuator-RF emulates a handheld radio-frequency remote control, enabling you to switch on and off power sockets at your property from anywhere in the world. Ideal for security (e.g. motion-controlled lights or alarms) or environmental applications (e.g. sensor-controlled heating and climate control).


actuator-r2-200x128Relay remote control

[Quatropus actuator] An Actuator-R2 enables you to remotely switch on and off two 0-30VDC circuits from anywhere in the world. Ideal for security (e.g. motion-controlled lights or alarms) or environmental applications (e.g. sensor-controlled heating and climate control) in boats, mobile homes, etc.


PHONE SENSORS


maxmon-plot-accelerationAcceleration

[Phone sensor] Uses the Android phone's built-in accelerometer to detect sudden motion, tilting or vibration. Ideal for security applications (e.g. a caravan or glider trailer being towed away), environmental applications (boat loose in berth) or a shake-to-alert feature for vulnerable individuals living alone.


maxmon-plot-batteryBattery

[Phone sensor] State of charge of the Android phone battery. The battery should only discharge if there is a power cut. A typical Android phone will continue monitoring and reporting (phone sensors only) for 12-24 hours. Disable GPS, accelerometer and sound sensor to extend battery life. See Battery backup.


maxmon-cameraCamera

[Phone sensor] Take photos of your remote property using the phone's built-in camera(s) and email them to yourself. You can take photos on a schedule, automatically in response to a sensor alert (e.g. motion) or manually via our remote control web application. You can use the main (rear-facing) camera on all supported Android phones, and LED flash or secondary (front-facing) camera on phones that have them.


maxmon-plot-locationLocation

[Phone sensor] Uses the Android phone's built-in location services (GPS and WiFi) to track the location of the phone (which might be inside a mobile property) and detect motion inside or outside configurable geo-fences. MaxMon provides two location sensors: one for raw latitude and longitude, the other for distance from a 'home' location. Ideal for security (e.g. tracking property location) or environmental monitoring (e.g. boat dragging anchor).


maxmon-plot-memoryMemory

[Phone sensor] The available phone storage in MB. Diagnostic-only, for monitoring the long-term health of the Android phone running the MaxMon app. If memory falls too low you may need to uninstall other apps and disable automatic updating of apps you cannot uninstall.


maxmon-plot-netNetwork

[Phone sensor] Monitors the data network to which the Android phone is connected (NONE, MOBILE or WIFI). Useful for monitoring the availability of shared WiFi networks (e.g. at a marina) and for diagnosing problems with the networking environment in which MaxMon is operating.


maxmon-plot-neterrNetwork (Errors)

[Phone sensor] Monitors the number of times the MaxMon app fails to connect to the Google email servers. Useful for monitoring the availability of shared WiFi networks (e.g. at a marina) and for diagnosing problems with the networking environment in which MaxMon is operating.


maxmon-plot-netokNetwork (OKs)

[Phone sensor] Monitors the number of times the MaxMon app successfully connects to the Google email servers. Useful for monitoring the availability of shared WiFi networks (e.g. at a marina) and for diagnosing problems with the networking environment in which MaxMon is operating.


maxmon-plot-powerPower

[Phone sensor] Monitors mains power (as received by the phone from its charger, often via a Quatropus). Ideal for detecting power cuts. During a power cut MaxMon will continue to run and report (phone sensors only) for as long as the phone's internal battery lasts (12-24 hours). Alternatively, you can power MaxMon from external batteries using a battery backup sensor.


maxmon-plot-soundSound

[Phone sensor] Monitors sound volume (as measured by the phone microphone) in units of accumulated kdB-seconds, making it easy to distinguish periods of low or high ambient noise. NOTE THAT THIS SENSOR DOES NOT RECORD OR REPLAY AUDIO. Useful for providing assurance that a remote location is not subject to (or the source of) noise pollution.
